mdtocs v1.0.4

mdtocs

Markdown table of contents generator:

mdtocs(string)

This library uses regex to parse Markdown headings. As a result, edge cases like headings with links and images won't be generated correctly. Inspired by the blog post.

Example

const { mdtocs } = require('mdtocs');
mdtocs('# Hello, World!'); // '- [Hello, World!](#hello-world)'

Install

NPM:

npm install mdtocs --save

Yarn:

yarn add mdtocs

CDN:

<script src="https://unpkg.com/mdtocs@latest/umd/mdtocs.min.js"></script>
<script>
  window.mdtocs.mdtocs(/* string */);
</script>

Usage

Import with ES Modules:

import { mdtocs } from 'mdtocs';

Or require with CommonJS:

const { mdtocs } = require('mdtocs');

Generate table of contents from Markdown:

mdtocs(`
# Heading 1
## Heading 2
### Heading 3
`);

Output:

- [Heading 1](#heading-1)
  - [Heading 2](#heading-2)
    - [Heading 3](#heading-3)

If the first argument is not a string, then an error will be thrown:

mdtocs(); // TypeError: First argument must be a string
